SPECIFICATION forming part of Letters Patent No. 411,769, dated September 24, 1889.

Application filed February ll, 188.9. Serial No. 299,476. (No model.)

To all whom it may concern: acting against the power of the weight B. Be it known that I, JOHN F. KINGWILL, a Secured to the dog B is the rod B4, its lower citizen of the United States, and a resident of end secured to the arm B5, projecting from Chicago, in the county of Cook and State of the rock-shaft B, from which projects also the 5 Illinois, have invented a new and useful Imarm B7, as shown in Fig. 2. This structure 5 5 provelnent in Coin-Controlled Blow Testing will remain in the position shown in Fig. 2 or Striking Machines, of which the following when the arm Bis raised and supported-as,

From an examination of contains the dial A', and through the dial 9o this structure it will be seen that when presspasses the shaft E', carrying the hand E2 and nre is applied or a blow struck on the cushpassing inward into the frame E3, which is seion A2 the rod A4, if free, will be oscillated cured to the inner side of the front of the on its pivot A5 against the action of the spring case. The shaft E is journaled in this frame A, but this barAis locked by means of the and in the cross-bar E4 behind the dial. 95 pivoted dog B, pivoted on `the hanger B, Rigid on this shaft E is the windlass and which is secured to the top of the case A. The the friction-plate E, provided with the lateral dog B has the weighted end B and the notch pin ES. B2, and above its inner or notched end is the E7 is a spring friction-bar, which bears L* 5o spring B3, which keeps it from rising too far, against and acts as a brake for said frictionroo plate E5. About the windlass E is coiled the cord E9, secured to the helical spring' E15, which is itself secured to the top of the case, and this cord E9 is secured at S12 to the windlass.

F is a drum loose on the shaft E' and having on one side (that next the plate E5) the pin F' to engage the pin E5, and on the other side the pin F2 to engage the pin F3, projecting from the frame E5. About this drum are coiled in opposite directions the cord G, secured to the spring G', which is in turn fastened to the bottom of the case, and the cord 'H, which passes over the pulley H', pivoted down the chute D into the scoop D2. Reference being had now to Fig. 3, it will be seen that the weight of this coin in the scoop D5, if the coin be of the right denomination, will be sufficient to counteract the influence of the spring D', rock the dog D on its pivot D2, and raise the lug D4 out of contact with the notch D5 and the end of the bar D5, as hereinafter stated. If the hand-lever C2 has been pushed down into the position indicated in Fig. 3 .and Fig. 2, the clock mechanism will be wound up to a certain degree, and as soon as the dog D is lifted outof engagement with the notch D5 andthe bar D8 the clock mechanism will begin to move the plate D5. In 0rder that the dog D may not re-engage the notch D5 before the mechanism has had time to move the plate D5, Ihave provided the bar D8, which as soon as released springs forward a certain distance beneath the lugI D4 of the dog. This bar D8 is .concentric with the plate D5, and its ends are arcs of a circle. The notches D5 D5 are on opposite sides of the plate D5, and the plate will continue to rotate and the clock mechanism to be in operation until the plate D5 is moved through one-half of its circumference, when the other notch D5 and the other endof the bar D8 will be engaged by the lug DA1 on the dog D. The relation of the pins C C to the notches D5 D55 is such that when one of these-notches is engaged by the lug D5,the pin is arrested at a point where it supports the arm B7, extending from the rock-shaft B5, as indicated in Figs. 3 and 2, and this turns the` rock-shaft B5 in its bearings and raises the arm B5 and rod B4, and hence turns the dog B on its pivot, so as to cause the shoulder B2 to engage the upper end of the rod A4, whereby said lattermentioned rod is locked in position. If a blow be struck on the cushion A2 while theparts arein this position, it is clear that no register will be made and that the -cushion will not move. Now, as soon as the plate D5 is moved any considerable distance, the pin C releases the end of the arm BT and permits the weight B' to cause the parts, including the dog B, to assume the position shown inv dotted lines, (see Fig. 2,) thus freeing the upper end of the bar A5. In this manner the mechanism is unlocked by means of the introduction of a coin through the chute D15. The scoop D3 is so made as not to respond to any but a coin of the right size and weight. The parts will thus remain unlocked until the arm B7 is again engaged and supported by one of the pins C, and this will not take place until the plate D5 is again locked, as shown in full lines in Figs. 2 and 3. If, now, a blow be struck at any time (when the parts are so released or unlocked) upon the cushion A2, it, with its rod A2, will be forced inward, rocking the rod A4, compressing the spring A11, and, by means of the c ord Hpassing over the pulley H', will rotate the drum F. These parts are shown in Figs. 4 and 2. The rotation of t-he drum F, however, since it must rotate in the direction indicated by thearrow in Fig. 4, will carry with it the frictionplate E5 and windlass E5, secured thereto and to the shaft E". This is accomplished by the engagement of the pin F', projecting from the side of the drum, with'the pin E5, projecting from the side of the friction-plate. Now, since the friction-plate E5 and windlass E5 are rigid on the shaft E', and the hand E2 is also rigid on such shaft, this hand will move in the direction indicated by the arrow in Fig. l, and hence will indicate the strength of a blow directed against the cushion A2. Now, of course, as soon as the pressure is removed from the cushion A2, or as soon as the force of the blow is lost, the spring A11 (shown in Fig. 2) reacts, restores the rod A4 to its normal position, slackens the cord H, and permit-s the spring G' .to unwind the drum in the opposite direction froln that indicated by the arrow in Fig. 4, or until its motion is stopped at substantially the ini- Ico IIO

tial point by the engagement of the pin F2 n it has reached, so as to give opportunity toread the indication; hence it is that the drum F is not rigid with the shaft E' or with the friction-wheel thereon, and hence it is that I have provided the spring frictionbar E7, which bears againstthe side of the friction-plate E5, and which retains the said plate and hence the shaft ,and indicatinghand in the position they reachA Now, this indication having been read, it is only necessary to force inwardly the push .I (shown in Fig. 2) until the friction-bar E' is freed from the friction-plate E5, when the drum E5 and shaft E and hand E2 will be restoredto their normal positions bythe reaction of the spring El drawing upon the cord E9. In like manner tests can continuato be taken until the clock mechanism has run down suficient to cause the dog D to again engage one notch D5 and one end of the bar D8, when the parts are again locked and can be opened only by the introduction of a coin. By lowering the hand-lever C2 the clock mechanism will again be wound up, and when released will continue to run for a period of, say, one or two minutes, during which a number of tests can be made.` The dog B, which locks the bar A4, together with the clock mechanism which controls such lock, I call the time-lock. The object of the spring-connection between the cord H on the drum and the bar A4 is to compensate for the inertia of the moving indicating parts, and it prevents breaking of such cord when the blow is given.

I claim as new and desire to secure by Letters Patentl. In a coin-controlled testingmachine, the combination of a testing apparatus, a lock therefor, a clock mechanism which controls such lock, and a coin-controlled release for such clock mechanism.

2. In a coin-controlled testing-machine, the combination of an apparatus with a lock therefor, a clock mechanism which when at rest holds such lock in engagement and when in operation leaves the same free, and a coin-controlled catch for such clock mechanism.

In a coin-controlled testing-machine, the combination of a pivoted bar with Va spring on one side and a striking-cushion on the other connected therewith, a lock which normally prevents the bar from rocking, a clock mechanism which controls such lock, and a coin-controlled catch for such clock mechanism which normally prevents said clock mechanism from moving and thus from yreleasing the lock.

5. In a coin-controlled testing-machine, the combination of a testing apparatus with a time-lock therefor independent of said testing apparatus when the same is released, and a coin-controlled catch for such lock which, when operated by a coin, releases said lock, and thereby releases the testing apparatus and after a predetermined period of time antomatically again locks the same independent of any operation of said apparatus.

6. In a coin-controlled testing-machine, the combination of a testing apparat-ns with a lock thcrefor,a time mechanism which,when in operation, releases said lock for a considera-ble period, and a coin-controlled catch for suchtime mechanism which normally holds it out of operation and adapted to release the time mechanism when the coin is introduced.

7. In` a coin-controlled testing-machine, the combination of a testing' apparatus with a lock therefor, a clock mechanism controlling said lock, anotched disk rotated by the said clock mechanism, connections therefrom to the lock so as to hold the apparatus locked whenthe clock mechanism is not in motion, and a dog which engages a notch on such disk at one end and locks the disk and carries' a scoop atthe other to receive the coin and release the dog from said disk and allow the same to rotate and release said apparatus.

8. In a coin-controlled testing-machine, the combination of a testing apparatus with a lock therefor, a clock mechanism, a disk ro tated by the said clock mechanism, and connections therefrom to the lock, so as to hold the apparatus locked when the clock mechanism is not in motion, a dog which engages a notch on such disk at one end and carries a scoop at the other to receive the coin, and aspring-bar pivoted on such disk adapted as soon as the dog is raised to slip under the end thereof and prevent the clock mechanism from again being locked until it has made a portion of its revolution.
